David Letterman’s 33-year run on late-night television was marked by his acerbic sense of humor.
Upon retiring in 2015, he’s undergone a metamorphosis into someone almost unrecognizable from the more comedic guy people watched on the “Late Show with David Letterman”.
He’s grown a full beard, which coupled with his balding head, makes him look like a guy wanting to moonlight as a department store Santa Claus.
But beneath that kindly-looking exterior lurks a clearly bitter and troubled man, as evidenced by recent nasty remarks about President Donald Trump.
It’s spelled out on the next page. See how the funny guy seems to have lost his sense of humor.

He needs a hobby.
If I were you I would not call Trump ignorant just look in a mirror.
Moron
The only ignorant people are people who will not assimilate to our way of life, and the ignorant ones want to keep them porting them into this country.
Another demented idiot
Right on!!!!
His old age is catching up to him
I don’t see any Applaud signs anywhere to make people think you actually have anything smart to say..Stay retired and shut the$#%&!@*Up .Nobody wants to hear what you have to say…They didn’t then and don’t now.
Go away and die Letterman…..scumbag
Never liked or watched him.
